struction of a signaling-device adapted to be manually setand released,and when released to transmit its signal independently of the manuallyoperated actuatmg-means,

whereby the transmission of the signal is then entirely'out of thecontrol of the op erator; also to construct a signaling-device, wherebythe signalingcircuit contacts are closed only a short but predeterminedperiod of time, long enough, however, to cause the operation of acertain recording-instrument or other si'gnalreceiving device which maybe employed to receive the signal, but not long enough to operate othersignal-receiving instruments which may be used in conjunction therewithand adapted to respond to other signaling-devices; also to provide thesignaling-device with means for temporarily trapping the. key, while thesignalingdevice is being set. Such a signaling-device is of particularimportance in signal-systerns, such as shown in my application for lLetters Patent #555,602 filed April 15,

1910, Where two sets of signaling-devices are employed; one adapted toclose the circuit for short periods of time and the other for longerperiods of time, the closures of the circuit for the different periodsof time being employed as a means of differentiation. Such asignaling-device is also adapted for 1 other uses.

The signaling-device embodying my invention comprises circuit-closingmembers,

an operatingdevice therefor, an actuatingspring for saidoperating-device, a winding or actuating-member for said spring adaptedto be operated by a key or otherwise, manually,'and means for arrestingthe operating-device while the actuating-member is being operated towind the spring and for releasing said operating-device when said.actuating-member has been moved forward a sufficient distance toproperly wind the spring, and for arresting" the actuatingmember whenthe operating-device is released, to thereby hold said actuating-memberwhile the operating-device is operating the circuit-closing members andthus prevent any manipulation thereof which might interferewiththeproper transmission of the signal. The signaling-device also includesmeans for subsequently releasing said actuating-member and permittingthe return of the parts to normal.

The signaling-device also comprises means for temporarily trapping thekeywhile it is being turned to set the signaling-device in condition totransmit its signal and to release the signaling-device thus set,permitting its withdrawal however, only, when the signaling-device has.been set and released, thus insuring the proper transmission of'thesignal whenever the key is inserted and turned.

0/. represents a suitable shell or case containing the operating-partsand the supportmove said pawl toward the ratchet-wheel.-

' The ratchetwheel b has a deep notch 6, out i in its edge, which isformedwith straight side walls, and the pawl (Z normally occupies aposition with its lug d at said notch, but held out of the deep portionthereof by a lug If, as shown in Fig. 2 which projects forward from theplate It on the escapewheel. At the beginning of the forward movement ofthe ratchet-wheel said pawl is lifted by the inclined side of-the deepnotch of'the ratchet-wheel engaging the lug (Z and its cross-piece (Z israised and held-in the path of movement of the lug h on theoperating-device, to thereby arrest forward movement of said operatingdevice, and said pawl will be held in such engaging position by theratchet-wheel, while the latter revolves,even when bottoming in theinterdental spaces, and until the deep notch b is again brought intoposition beneath the lug 03 During this time saidpawl also acts toprevent backward rotation of the ratchetwheel by engaging theratchet-teeth thereof.

In Fig. 4, the ratchet-wheel is represented as partly turned, the pawlis elevated, the crosspiece d thereon is engaged by the lug h, and theoperating-device is arrested. When the ratchet-wheel has been turned acomplete revolution or. thereabout and theactuatingspring has beenwound, it is then necessary to disengage the lug h from the pawl topermit the operating-device to be revolved by the actuating-spring,independently, and to accomplish this result, at this particular timeonly, the deep notch b in the ratchet wheel arrives in position beneaththe lug (Z on the pawl, and said pawl being no longer held in elevatedposition by the ratchetwheel, is moved by the pressure of the lug itupon the cross-piece d far enough to permit the high to pass over thecross-piece. The lug it being thus disengaged, the operating-device willbe revolved by the spring in the same direction as the actuatingmemberwas turned to wind theactuating-spring. As the pawl is moved todisengage the lug h, its lug d enters the square part of the notch 6 farenough to positively lock the ratchet-wheel, see Fig. 5, and in suchposition acts to hold the actuating-member at rest while theoperating-device revolves independently thereof. Vhen the pawl thusenters the square part of the notch?) and looks the ratchet-wheel, itwill be prevented from being removed therefrom while theopcrating-device is revolving by the inner edge of the ring j, on said.operat-ingdevice, which moves over the crosspiece during such time. Thisring f", however, has a notch 7 also on the inside, which arrives inposition above the cross-piece as the operatingdevice resumes its normalposition to allow the pawl to be again lifted. Just before the0peratingdevice comes to rest the lug 7L2 on the plate h and extendingforward from it, will engage the cross-piece (Z and lift and hold thepawl above the squared left hand side of the deep notch 5 thus againreleasing the ratchet-wheel for another operation.

It will thus be seen that while the actuatingmember is being operated towind the actuating-spring, theoperating-device is locked, and whiletheoperating-device is moving to operate the circuit-closing members,the actn ating-member is locked, and for simplicity of construction thes ame-locking-device is employed for accomplishing both results, saidlocking-device being first moved by the i actuating-member to lock theoperating-device, and then temporarily held in locking position, andthen released to release the operating-device, and upon release of theoper ating-device is then moved by the operatingdevice "to lock theactuating-member, and finally is moved to release said actuatingmember.Thus the actuating-member and operating-device alternately controltheoperation of each other, each operating. to prevent the operation of theother during its own operation, but leaving the other free to operate atthe end of its own operation.

To arrest forward movement of the operating-device at the end of itscomplete revolution the forwardly extended lug 71 on the plate 72/, isarranged to travel in the path of movement of the lug 6 on theactuatingmember, and to engage said lug b, at such time; and, as at thistime the part to which the inner end of the actuating-spring is attachedis in engagement with the part to which the outer end of said spring isattached, said spring cannot further cause relative operation of eitherpart.

In Fig. 2, wherein the parts are represented in their normal positions,it will'be observed that the lug 71- on the operatingdevice is inengagement with the lug 6 on the actuating-member, but is disposed atthe back side of said lugbi so that the actuating-member is free to bemoved forward by the key. As the key is turned and the lug bratchet-wheel, the operating-device will follow until arrested by thelug h engaging the cross-piece 0Z It will also be observed that justbefore said ratchet-wheel has been turned a complete. revolution saidlug b will be brought to the opposite side is moved forward with the bya forward movement of the actuating.
